Abstract: An experiment was undertaken to evaluate the fourteen finger millet varieties (released and prereleased) including two check varieties viz., Indaf 5 (susceptible) and GPU-28 (resistant) against neck and finger blast disease at Agricultural and Horticultural Research Station, Bavikere, Chikmagaluru district, Karnataka during kharif 2014 to 2016. Varieties viz., VL-149, DM-7, PR-202, GPU-76, VR-948, BR-2, TNAU-1063, RAU-8, TNAU-1066, GPU-67, OEB-532 and PPR-2885 showed the immune reaction under natural field condition. The percent disease intensity of neck and finger blast ranged from 0.00 to 28.71 and 0.00 to 33.36 respectively, where it was 28.71 and 33.36 PDI in check Indaf-5 Moderately susceptible reaction respectively. In case of finger blast, disease severity ranged from 0.00 to 24.18 percent, and it was 33.10 PDI in susceptible check Indaf-5 showed highly susceptible reaction. The resistant check variety GPU-28 exhibited resistant reaction to both neck and finger blast. With respect to yield performance, the genotype GPU-67 recorded significantly higher grain yield of 43.12 q/ha but found on par with VR-948 (42.17 q/ha) and OEB-532 (41.10 q/ha) respectively.
